A positioning device for an adjustable TRT stationary blade mechanism

Abstract

This utility model discloses a positioning device for an adjustable TRT stationary blade mechanism, relating to the field of TRT stationary blade technology. The ring assembly includes a ring, with a fixed post fixedly connected to its outer wall. A rotating shaft is disposed outside the fixed post, and a connecting buckle is fixedly connected to the outer wall of the rotating shaft. A rotating groove is formed in the wall of the connecting buckle. By setting a locking block, the locking block can be manually moved to rotate the ring. The fixed post on the ring will then drive the rotating shaft to rotate via the connecting buckle. The rotating shaft drives the fan blades to rotate, enabling synchronous adjustment and control of multiple blades. When the appropriate angle is reached, the locking block is released, and the spring force in the locking block pulls the locking block, causing it to slide downwards within the locking block. This allows the locking block to be engaged in the locking groove of the chuck, achieving long-term stable operation.

Description

Technical Field

[0001] This utility model relates to the field of TRT stationary blade technology, specifically a positioning device for an adjustable mechanism of TRT stationary blades. Background Technology

[0002] The stationary blades of the TRT are installed inside the turbine cylinder and arranged in a ring on both sides of the moving blades. They are an important part of the turbine and are used to guide the airflow, directing the high-pressure gas from the blast furnace into the moving blades in a specific direction and at a specific speed.

[0003] In the existing technology, the traditional stationary blade adjustment mechanism often uses multiple independent drive components to control the rotation of each blade. This method is not only structurally complex, but also makes it difficult to ensure the synchronization of multi-blade adjustment. Due to the differences in the operation of each drive component, the angle changes of different stationary blades are inconsistent during the adjustment process, which will lead to uneven distribution of gas flow in the turbine, thereby affecting the stability of the moving blade under force.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-5 This utility model provides a technical solution comprising: a disc 1, a blade assembly 2 rotatably connected to the inner wall of the disc 1, an annular disc assembly 3 disposed on the outer side of the disc 1, a chuck assembly 4 fixedly connected to the outer side of the annular disc assembly 3, the annular disc assembly 3 including a ring 31, a fixing post 32 fixedly connected to the outer wall of the ring 31, a rotating shaft 34 disposed on the outer side of the fixing post 32, a connecting buckle 33 fixedly connected to the outer wall of the rotating shaft 34, a rotating groove 35 formed in the wall of the connecting buckle 33, the outer wall of the ring 31 slidingly connected to the outer wall of the disc 1, the outer wall of the fixing post 32 slidingly connected to the inner wall of the rotating groove 35, the fixing posts 32 being arranged in a ring array along the central axis of the ring 31, and the blade assembly 2 including a connecting ring 21. A rotating shaft 23 is rotatably connected to the outer wall of the connecting ring 21. A TRT stationary blade 22 is fixedly connected to the outer wall of the rotating shaft 23. The rotating shaft 23 is arranged in a ring along the central axis of the connecting ring 21. The outer wall of the rotating shaft 23 is rotatably connected to the inner wall of the disk 1. The end of the rotating shaft 23 away from the connecting ring 21 passes through the disk 1 and extends to the outside of the disk 1 and is fixedly connected to the outer wall of the rotating shaft 34. The further advantage of the above is that by setting a locking block 43, the locking block 43 can be manually moved to drive the ring 31 to rotate. The fixed post 32 on the ring 31 will drive the rotating shaft 34 to rotate through the connecting buckle 33. The rotating shaft 34 drives the fan blade to rotate through the rotating shaft 23, which can realize the synchronous adjustment and control of multiple blades.

[0017] The chuck assembly 4 includes a chuck 41, with a groove 45 on its outer wall. A support block 46 is fixedly connected to the outer wall of the chuck 41. A groove block 42 is provided on the outside of the chuck 41. A locking block 43 is slidably connected to the inner wall of the groove block 42. A spring 44 is fixedly connected to the outer wall of the locking block 43. The outer wall of the groove block 42 is fixedly connected to the outer wall of the ring 31. The outer wall of the support block 46 is fixedly connected to the outer wall of the disc 1. The outer wall of the locking block 43 is slidably connected to the inner wall of the groove 45. The end of the spring 44 away from the locking block 43 is fixedly connected to the inner wall of the groove block 42. The further advantage of the above is that when the angle is adjusted to a suitable position, by releasing the locking block 43, the elastic force of the spring 44 in the groove block 42 pulls the locking block 43, and the locking block 43 will slide downward in the groove block 42, so that the locking block 43 can be firmly locked in the groove 45 of the chuck 41, achieving long-term stable operation.

[0018] Working principle: First, when adjusting the fan blades, manually pull the locking block 43 in the locking block 42 to make the locking block 43 slide in the locking block 42, so that the locking block 43 disengages from the locking slot 45 in the chuck 41, releasing the locking block 42. At this time, the locking block 43 can drive the locking block 42 to rotate. By manually turning the locking block 43, the locking block 42 is moved, causing the locking block 42 to drive the fixedly connected ring 31 to rotate. During the rotation of the ring 31, the fixed column 32 of the array fixed connection will also rotate. During the movement of the fixed column 32, the fixed column 32 slides in the rotating groove 35, thereby turning the connecting buckle 33 to move, so that the connecting buckle 33 drives the rotating shaft 34 to rotate on the disc 1. By fixing the rotating shaft 34 to the rotating shaft 23, the rotating shaft 23 rotates on the connecting ring 21, thereby driving the TRT stationary blade 22, which is fixedly connected to it, to rotate. The angle of the TRT stationary blade 22 can be adjusted to achieve synchronous adjustment and control of multiple blades. When the appropriate angle is adjusted, the locking block 43 is released, and the elasticity of the spring 44 in the locking block 42 is used to pull the locking block 43 to move. At this time, the locking block 43 will slide and reset in the locking block 42, so that the locking block 43 is locked in the locking slot 45. At this time, the locking block 42 cannot drive the ring 31 to rotate, thereby completing the fixing of the TRT stationary blade 22 after angle adjustment.
